GASOLINE RESERVE VALVE.

Application filed October 8, 1921. Serial No. 506,450. y

To all whom t may concern.'

Be it known that we, EDWARD J. ,STADDER and EDWARD SoHoLz, citizens of theUnited States, residing at Chicago, in the county yof.

either gravity feed or vacuum feed-systems,V

wherebythellow of gasoline between the supply tanky and the carburetorjis shut olf when the gasolinehas reached a predetermined level in the tank, there remaining a reserve quantity of gasoline in the tank, said valve having` means whereby the flow may be continued to thence use up the reserve supply. When the supplyhas been cut off, it

indicates to the operator that only the re-y i serve supply of gasoline remains, whereupon the valve may be actuated so as to make use of itto enable him to freach a point where he can receive a fresh supply. w ,f n .The invention has among its objects the production of a device ofthe kind described which is simple, convenient, compact, du-

. rable, reliable, `efficient and satisfactory for use `wherever found applicable.

.Tolthis end our invention consists in thev novelconstruction, arrangement and combination of parts herein shownand describedv .,andmore particularly `pointed out in the r claims.

Inthe drawings,wherein we have illus-v trated the preferred vembodimentof our invention, l1 indicates the fuel supp'lytank,

` saidtankbeing ofany desired shape and ma terial, located as desired The fuel 3 insaid ytank is fed to the carburetor y(not shown) through the e, valve V, said tank having an outlet 2 formed therein as at the topy as shown, and preferably internally threaded to receive the valve V. lIn themodilication,y shown, Vthe outlet 2 is made up ofia pipe pore tion lwith a flanged base which is secured to the ltank by any suitable means,as by Weld-l mg, riveting or the like.

forming an annular 'shoulder 7 at'its juncture with the portion 5; An annular groove 8 is formed` in the member adjacent the shoulder 7 andcommunicateswith a lateral duct 9 which extends longitudinally thereof from the bottom end of the member and terminating at said annular groove, the bottom or innerendkof saidv member having an enlarged, outwardlytapered conicaly seat l2 to `vcooperate with the r.valve member 14 to bel hereinafter described.

The collar 10 threadedfportion having a bore 8 there' through communicatingwith the-annular groove 8. An outlet `-or discharge pipe leading' to the carburetor, and having an annularlyenlarged end 1l.` may be detachf ably secured in registry with the bore 8',

by any suitableror preferred means, as bv is vdischarged through the pipe 11.

Coaxial with the conical seat l2 and exe tending kaxially y,through saidfvalve member from one end to the other 'thereisprovidedabore 13.k `Fitting within the borel andy projectingbeyondthe outer end thereof,vis a stem' v17 "threaded" at its upper end as at' 21 andthe lower inner end thereof enlargedg and conically tapered to form a'conical valve adapted to enter the conical vvalve anut v10.whereby-the fluid drawn through the duct vE9e-enters the annular groove Sand seat 12and bearthereupon. A-pair of ducts i 15 and `16. are provided longitudinally, of;

the conical? valve portion 14 and spaced circumferentially thereon, said ductsbeingadapted to register alternately with the duct 9 when the valve part 14 is rotated to the proper position, one oi the ducts 15 or 16 being out of registry with the duct 9 wherever the other duct is in registry therewith. As shown, extension pipes 19 and 2O are arranged at the ducts 15 and 16 respectively, one of said pipes, as forv instance, the pipe 19, being of lesser length than the pipe 20, so that when the duct 15 is in communication with the duct 9, the liquid from the tank will be withdrawn until said liquid falls to the level indicated at 4. rlhen, in order1 to drain the remaining liquid from the tank, the valve member 141 is partially lrotated se as'to place the pipe` 2O in communication with vthe duct 9. p

At the upper end of the stem 17 is arranged a cap or nut 23 having an enlarged arial opening 24 therein adapted to receive a spring 25, said saring tending to move or urge the valve member 14 against ,the valve seat 12 and to compensate for wear and prevent leakage therebetween. it. washer 26 may be' inserted between the lower end'foit the spring and the top Ytace of the valve part 6, it so desired. A lock nut 22 or the like may be threadedly secured to the end of thestem beyond the nut so as to prevent the accidental displacement of the nut 23 and to protect the threads on the end ot the stein.

Y n the upper face of the annnlarly enlarged portion 6 there are provided a pair of detents 27-27 which areadapted to receive a ball 29 pressed by a spring 30,-said spring Afitting into a recess 28 in the member 23.v ln this manner the operating` positions of the valve are determined by the ball, which is yieldably depressed into said detents. rEhe enlarged portion 6 has an indicating mark 31 for example, and arrow, provided thereon, which is adapted to co` operate with a pair of marks 32 and 33 on the rotatable member 23, so that the operator may quickly determine which ot the duct or 16 are in registry with lthe duct 9.

Assuming that the duct 16 is closed at its upper end against the valve seat 12, and the duct 15 is in registry with the duct 9, then the gasoline in the tank 1 will be withdrawn through the duct 9 until it reaches the pre determined level 1, dependent upon` the length of the pipe 19, whereupon the feed through the duct 15 will cease. This indicates to the operator that the reserve supply has been reached, and he being warned, turns the member 23 until the ball 29 falls into the proper detent`27 and the arrow 31 is in registry with the nia-rk 33. This movement of the valve 14 opens the duct 16 into registry with the duct 9, so` that the reserve quantity of gasoline may flow through the" ducts 16 and 9 to the carburetor, enabling the operator to reachv 'a point where additional uel may be? puro iased or secured.

ln case it is desired to use the valve for agravity feed system, the valve would be placed at the bottom of the tank 'so that the ducts 19 and 2O would extend upwardly thereinto. Then the longer duct, i. e. the

rone projecting further into the tank would conduct the liquid until the reserve level was reached, whereupon the valve would be operated to throw the shorter duct into registry with the opening 9 to permit the reserve supply in the tank to be drained.

lt will be noted that any predetermined proportion of gasoline may be considered as a reserve supply, this'reserve supply being'thev difference between the quantities corresponding to the difference in level between the ends of the inlets to the two ducts. rllhe connection with the tank and pipe line may be varied as required, depending upon the articular installation.

Hlziving` thus described our invention, it is obvious that various immaterial modifications niay be made in the same without departing from the spirit of our invention; hence we do not wish to be understood as limiting ourselves to the exact form, construction, arrangement and combination ot parts herein shown and described, or uses mentioned. 1
